Here's a cool idea: At Rank 6 Gunsmith, and with Exotic Sword Quest completed, give us a quest for 3 new unique Legendary Swords, but manufactured/powered by Weapons Foundry Technology instead of that shard Eris took from Willbreaker. Imagine the look of an Omolon Sword (Lightsabre?), Hakke Sword (Guilty Gear) or SUROS Sword (Power Ranger Toy... LOL j/k no idea what that would look like)....
